NOTE This manual has been developed for a unit fitted with all available options. Inputs/outputs, functions, configuration screens and other details described, which do not exist on your unit may be ignored. The present manual has been prepared to enable the installation and commissioning of the unit. Because of the large variety of parameter settings, it is not possible to cover every possible combination. The manual is therefore only a guide. In case of incorrect entries or a total loss of functions, the default settings can be taken from the enclosed list of parameters. Page 10/114 Woodward

11 Chapter 2. easygen Series 300 Overview The easygen Series 300 consists of four models which are intended for different applications and requirements. This manual covers all available versions of the easygen Series 300. Please take information about the differ- between the units from this ences section. Functionality \ easygen [320] [320X] [350] [350X] Generator measurement Mains measurement GCB MCB MPU ( pickup) Input CAN bus J Table 2-1: easygen series 300 product features NOTE Some parameters of the easygen-300 series can only be configured using the Direct Configuration Cable DPC (P/N ) and a notebook/pc with the software LeoPC1. These parameters are indicated with an L in the parameter description under Parameters starting from page 64 and can not be configured at the unit directly. The c onfiguration with LeoPC1 via the DPC is described under Configuration Using the PC on page 61. The DPC is n ot part of the easygen-300 shipment and sold separately (P/N ). IMPORTANT NOTE ABOUT COUNTERS The counters for Operation hours Maintenance Interval Number of starts can be recalibrated with LeoPC1 and the configuration files belonging to the unit. If 3 rd party users are not allowed to change these values, you can easily remove the parameters which enable changing the counters by editing the LeoPC1 configuration files as described under Editing the Configuration File on page 62.

12 Chapter 3. Electrostatic Discharge Awareness All electronic equipment is static-sensitive, some components more than others. To protect these components from static damage, you must take special precautions to minimize or eliminate electrostatic discharges. Follow these precautions when working with or near the control. 1. Before performing maintenance on the electronic control, discharge the static electricity on your body to ground by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.). 2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials. Wear cotton or cotton-blend materials as much as possible because these do not store static electric charges as much as synthetics. 3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the control, the modules, and the work area as much as possible. 4. Opening the control cover may void the unit warranty. Do not remove the Printed Circuit Board (PCB) from the control cabinet unless absolutely necessary. If you must remove the PCB from the control cabinet, follow these precautions: Ensure that the device is completely de-energized (all connectors must be disconnected). Do not touch any part of the PCB except the edges. Do not touch the electrical conductors, connectors, or components with conductive devices with your hands. When replacing a PCB, keep the new PCB in the protective antistatic bag it comes in until you are ready to install it. Immediately after removing the old PCB from the control cabinet, place it in the protective antistatic bag. CAUTION To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715, Guide for Handling and Protection of Electro nic Controls, Printed Circuit Boards, and Modules.

14 For installation into a door panel, proceed as follows: Installation 1. Panel cut-out Cut out the panel according to the dimensions in Figure Remove terminals Loosen the wire connection terminal screws on the back of the unit and remove the wire connection terminal strips if required (1) Loosen clamping screws Loosen the four clamping screws (1) until they are almost flush with the clamp inserts and tilt the clamp inserts down by 45 (2) to remove them from the housing. Do not completely remove the screws from the clamp inserts Insert unit into cut-out Insert the unit into the panel cut-out. Verify that the unit fits correctly in the cut-out. If the panel cut-out is not big enough, enlarge it accordingly. Ensure that the gasket is placed properly if used. 5. Attach clamp inserts Re-install the clamp inserts by tilting the insert to a 45 angle (1). Insert the nose of the insert into the slot on the side of the housing. Raise the clamp insert so that it is parallel to the control panel (2) Tighten clamping screws Tighten the clamping screws (1) until the control unit is secured to the control panel (2). Over tightening of these screws may result in the clamp inserts or the housing breaking. Do not exceed the recommended tightening torque of 0.1 Nm Reattach terminals Reattach the wire connection terminal strips (1) and secure them with the side screws. 1 Note: If the gasket is damaged, it needs to be replaced. Use only the original gasket kit (P/N ) for replacement. Page 14/114 Woodward

32 Chapter 7. Operation and Navigation Figure 7-1: Front panel and display Figure 7-1 illustrates the front panel/display which includes push-buttons, LEDs and the alphanumerical 7 segment LED display. A short description of the front panel is given below. NOTE This push-button is ALWAYS enabled and will stop the engine when pressed Push-buttons The push buttons on the front panel are assigned to fixed functions of the unit LEDs The LEDs indicate operating states of the unit and alarm messages. The right LED indicates that alarm messages are present in the unit segment LED display This alphanumerical display is used to display all measured values, operating parameters, and alarm messages. A description of this display is detailed later in this manual. Page 32/114 Woodward

33 Purpose of the Status LEDs Operation and Display The easygen has several status LEDs to indicate the operating state. The LEDs indicate the following conditions: LED 9 : Mains voltage present (only easygen 350 and 350X) LED 10 : Mains circuit breaker (MCB) closed (only easygen 350 and 350X) LED : Generator circu it breaker (GCB) closed LED 12 (on): Generator in operation LED 12 (flashing): Generator voltage and/or frequency are not within the Breaker Closure Limits (see page 54) LED 13 (on): Engine in operation LED 13 (flashing): Engine in operation, but engine monitoring delay time (see page 68) not yet expired LED 14 : Alarm message present LED 15 : Genset in automatic operation LED 16 : Genset in manual operation LED 17 : Genset stopped A function test of all LEDs and the seven-segment display may be conducted by pressing the 7 and 8 buttons simultaneously. Operating the easygen When the easygen control unit is powered up and the genset is not operating, LED 17 is illuminated and the MCB is closed (only easygen 350 and 350X). The control unit may be started in automatic mode or have the operation mode changed from automatic to manual by pressing the Auto - Manual button 3. LED 15 (automatic) or LED 16 (manual) will indicate the current mode of operation by the corresponding LED being illuminated. The Breaker Control button 4 enables the operator to open or close the circuit breaker(s) depending on the current state of the breaker and the control unit being in manual operation mode. This button is disabled in automatic operation mode. The Start/Stop Engine button 5 will start and stop the engine when the control unit is in manual operation mode. This button is disabled when the control unit is in automatic operation mode. The Stop button 6 is always enabled and when pressed while in the automatic mode will shut the en- gine down after the configured cool down period has expired. Pressing this button twice will shutdown the genset immediately. Active alarm messages may b e acknowledged with the Alarm button 2. Alarm conditions are indicated when LED 14 is illuminated. When the easygen is in normal operation, the operator may view the monitored parameters by using the Scroll button 1. The monitored values will be displayed on the 7-segment display 18 (a detailed description of the displayed operating values may be found later in this manual). Acknowledging Alarm Messages LED 14 will flash when an alarm is active. The alarm message will be displayed in the 7-segment display 18. Pressing the alarm button 2 will acknowledge the alarm, reset the alarm relay (if relay is configured for alarm input), and the LED will change from flashing to continuously illuminated. If more than one fault condition is present, the operator may display these messages by pressing the Scroll button 1. The alarm may be deleted by pressing and holding the Alarm button 2 a second time until the LED 14 is no longer illuminated. If the fault condition is still present, the LED 14 will remain illuminated and the unit stays in a locked mode according to the appropriate alarm condition. Woodward Page 33/114

51 Operating Mode AUTOMATIC In the AUTOMATIC ope rating mode, all engine, GCB, and/or MCB functions are operated via the discrete inputs or automatically by the control unit ( i.e. a mains failure). The function of the easygen depends on the configuration of the unit and how the external signals are us ed. LED 15, in the upper left corner of the AUTO - MANUAL button 3, indicate s the automatic operating mode.

53 AMF / Auto Mains Failure Operation - [350], [350X] The operation sequence for an AMF operation is similar to the above sequence with the difference that a remote start signal is not required for the engine start and the engine monitoring delay time is not considered, i.e. the CBs are operated immediately. For an AMF operation in automatic mode the parameter Emergency power monitoring (page 69) must be configured to ON, no class F alarms may be present, the engine must be ready for op- eration, and the configured mains fail delay time (page 69) must expire to start the engine. Example for an AMF Operation: Initial situation: Mains are present Mains circuit breaker is close d The generator controller is in the automatic operation mode and emergency stand-by A mains failure occurs: Mains are not present Reaction of the unit: The mains failure is detected by the unit The period configured in the parameter "Mains fail delay time" expires The period configured in the p arameter "Preglow time" expires The generator will be started The mains circuit breaker will be opened The time configured in the parameter "Transfer time GCBMCB" expires The generator circuit breaker will be closed The unit is in auto emergency power operation now T he mains return: The return of the mains is detected by the unit The period configured in the parameter "Mains settling time" expires The generator circuit breaker will be opened The "Transfer time GCBMCB" and "Cool down time" timers start to run If the time configured in the parameter "Transfer time GCBMCB" expires, the MCB will be closed If the time configured in the parameter "Cool down time" expires, the generator/engine will be shut down The unit is back in emergency stand-by Mains failure Mains fail Preglow time Genset start Engine de- GCB delay Open MCB Transfer Close GCB AMF opdelay time (configurable) lay (fixed: 8 (fixed: 2 time GCB eration ( configur- seconds) seconds) MCB (conable) figurable) This period is ignored for AMF operation Woodward Page 53/114

These limits depend on the parameters rated system frequency and rated generator voltage (see Measuring on page 65) and cannot be changed. The limits are set as follows: f generator must be within f rated system +/- 10 % Examples: If the rated system frequency is set to 50 Hz, the upper limit is at 55 Hz and the lower limit is at 45 Hz. If the rated system frequency is set to 60 Hz, the upper limit is at 66 Hz and the lower limit is at 54 Hz. V generator must be within V rated generator +/- 10 % Examples: If the rated generator voltage is set to 400 V, the upper limit is at 440 V and the lower limit is at 360 V. If the rated generator voltage is set to 120 V, the upper limit is at 108 V and the lower limit is at 132 V. 12 If the generator voltage and/or frequency is/are not within these limits, the generator LED is flashing and the GCB cannot be closed. If the generator voltage and frequency are within these limits, the generator LED 12 is permanently on and the GCB may be closed. Page 54/114 Woodward

55 Functional Description of the Oil Pressure Input DI1 The easygen 300 series is provided with an input for oil pressure. The function of this discrete input is described in the following. Vdc (GND) GND (Vdc) Discrete input DI1 (oil pressure) Oil pressure switch Figure 8-2: Discrete input DI1 - oil pressure Terminal Description A max 15 DI1 oil pressure common 2.5 mm² 16 DI1 oil pressure signal 2.5 mm² Table 8-1: Discrete input DI1 - oil pressure The oil pressure switch is connected to the terminals 15 (common) and 16 (DI1 signal) on the easygen 300. The oil pressure switch (OPS) must be a N.C. contact. If the oil pressure is below the minimum required pressure, the contacts need to close. If the oil pressure is above the minimum required pressure, the contacts need to be open. The oil pressure is only monitored if the easygen detects speed/frequency from the genset. If the genset is in a stand-by or stop mode, the oil pressure switch is disabled. Parameter "Crank termination by DI1" If the parameter "Crank termination by DI1" is enabled, the oil pressure can be used to terminate the starting system for the engine. 2 seconds after oil pressure is detected, the crank relay will be disabled. The delay ensures that the crank relay is not disabled prior to the engine reaching firing speed. Parameter "Starter time" In all other applications, the starter is active only for the time configured in the parameter "Starter time". The following diagram shows the starting procedure as a function of time. Figure 8-3: Starting procedure Woodward Page 55/114

56 Firing Speed Detection The firing speed is used for crank termination if the parameter "Crank termination by DI1" is not enabled (refer to Parameter "Crank termination by DI1" on page 55 if this parameter is enabled). When "Crank termination by DI1" is disabled, the firing speed is determined by the generator frequency or is calculated from the nominal speed and the rated system frequency. The control unit shows the following behavior: Case 1: Firing speed is reached if a minimum generator frequency of 15 Hz is detected. The easygen versions [320] and [350] operate in this manner. It is possible for the easygen versions [320X] and [350X] to also operate in this manner if the parameter "Speed pickup" is disabled. Case 2: Firing speed is reached if the calculated firing speed is detected via an MPU. The easygen versions [320X] and [350X] must have the parameter "Speed pickup" enabled to operate in this manner. The firing speed is calculated according to the following formula: Firing Speed = Nominal Speed Rated System Frequency * 15 Hz Example: If the nominal speed is 1,500 rpm and the rated system frequency is 50 Hz, the firing speed will be (1,500 rpm / 50Hz) * 15 Hz = 450 rpm. The crank will be terminated if the calculated speed exceeds 450 rpm. Page 56/114 Woodward

57 Functional Description of the Charging Alternator Input/Output The easygen 300 series monitors the charging alternator operation with the following functionality. If the engine is started, the internal switch is closed simultaneously with the crank relay output, and the battery voltage is applied to the exciter winding D+ through the internal switch contacts. This pre-excites the charging alternator so that voltage is generated. The internal switch will be opened when the engine has started properly and the crank relay output has been de-energized to terminate the crank cycle. If the engine is driving the charging alternator, the battery will be charged from the charging alternator. Terminal 3 (for 24V systems or terminal 4 for 12V systems) now acts as the charging alternator input for monitoring the charging voltage. Terminal 2 (battery voltage +) serves as the input for measuring the battery voltage of the unit at the same time. Usually the alternator charges the battery while the engine is running. This ensures that the battery is charged and ready to energize the cranking circuit and other auxiliary components for the next start. In some cases the alternator itself needs excitation from an auxiliary source for generating its own terminal volt- In this case the battery will be connected into the alternator excitation windings during the engine start-up. ages. This ensures that the alternator will be self-excitated and provides voltage for charging the battery after the start- up sequence. The EasYgen provides two features: 1. Aux-excitation for the alternator 2. Continuous monitoring of the alternator terminal voltage The D+ Terminals are internal connected to the crank-relay-contacts: During engine-start up the battery will be connected across internal contacts and resistors to the D+ input of the alternator. The alternator will be excitated by the battery. Once the engine exceeds firing speed the internal switch opens and the D+ terminals will be disconnected from the alternator excitation windings. While the engine is running the D+ terminals are still connected to the easygen which will measure the terminal voltage of the alternator. If the voltage drops below a limit the easygen will initiate the fault "alternator charge failure". Depending on the battery system the easygen provides terminals for 12V and for 24V battery systems. The internal resistors limit the charge current for each of the two systems. 2 easygen-300 Battery B+ G~ D+ 24 Vdc 12 Vdc Ω 105 Ω internal switch Figure 8-4: Charging alternator input/output NOTE The charging alternator D+ acts as an output for pre-exciting the charging alternator during engine start-up only. During regular operation, it acts as an input for monitoring the charging voltage. Woodward Page 57/114

58 Functional Description of the 2 nd CB Close Delay Time The easygen-300 series provides Delayed close GCB and Delayed close MCB (only [350], [350X]) signals in the list of configurable parameters (find more details about this under Relay Outputs on page 83) in order to meet the requirements of some special circuit breaker types which require an Enable CB Close signal before the actual CB close signal. The function of these signals is described in the following text. If those CBs are utilized, they require two Close CB signals with a time delay in between from two different relays. This can be achieved by selecting Delayed close GCB (MCB) from the list of configurable parameters for a freely configurable relay (relay 3 or 4). The delay time can be configured with the parameter 2nd GCB (MCB) Close Delay Time. If the user initiates the command Close GCB (MCB), the signal is immediately issued from the fixed relay (relay2 for GCB or relay 1 for MCB) assigned to give the close command. After the configured delay time has expired, the second Close GCB (MCB) signal is issued. The user configures the delay time for the second close command at the relay output. Example for the functionality: Assumption: The close GCB signal is to be issued parallel on a second relay with a delay. Relay 4 shall be used in this example for this. The parameter "Relay 4" has to be configured to "Delayed close GCB" from the list of configurable parameters (refer to Relay Outputs on page 83). The delay time may be configured with the parameter "2nd GCB close delay time"(refer to Application on page 66). A period of 2 seconds shall be configured for this example. If the user triggers the command "Close GCB" now, the following sequence will be performed: The signal "Close GCB" energizes the relay firmly assigned to it (relay 2) immediately. After the configured delay has expired, the signal "Close GCB" energizes the relay assigned by the user (relay 4 in this example) with the configured delay. Signal: close CB t Signal: close CB with delay The delay "t" corresponds with the values of the parameters "2nd GCB close delay time" and "2nd MCB close delay time". If the respective circuit breaker is opened, both relays return to their initial state. NOTE This functionality can only be configured using LeoPC1. Page 58/114 Woodward

59 Functional Description of the Engine Released Signal The easygen 300 series provides the engine released signal in the list of configurable parameters (find more details about this under Relay Outputs on page 83). It is possible to use this signal for some special applications. Its functionality is described in the following for an emergency power supply. Emergency power supply syste ms often require that all external system components (i.e. governors, etc.) except the genset control be disconnected from the battery power supply and that the battery is not loaded unnecessarily during engine downtime. This means that the external components shall only be connected with battery power, if the engine is operating. To achieve this, a genset control signal is required, which connects the external components to the battery, as soon as the engine is started. This can be accomplished using the engine released signal when configuring a relay ( relay 3 [350], [350X] or 4) to initiate this signal. The functionality is described in the following text with relay 4. Relay 4: engine released easygen-300 Relay 5: fuel relay K1 Additional equipment (governors, auxiliary services, etc.) K1 K2 Battery The following functionality depends on the setting of the fuel relay (page 67): Figure 8-5: AMF application with engine released signal Fuel relay configured as operating solenoid: The easygen detects the mains loss and initiates the engine start. Relay 4 (configured to engine released) and rerelay provides the fuel supply to the engine. Relay 4 closes the contact lay 5 (fuel relay) are energized. The fuel K1 and connects the battery power to the external components that they are ready for operation. This ensures that these external components are not energized until they are needed. Fuel relay configured as stop solenoid: The easygen detects the mains loss and initiates the engine start. Relay 4 (configured to engine released) is energized. Relay 4 closes the contact K1 and connects the battery power to the external components that are needed for operation. This ensures that these external components are not energized if they are not used. If the engine is stopped, relay 5 (fuel relay) will be energized, cutting off the fuel supply. NOTE It is not recommended to use the fuel relay signal for connecting the external equipment with the battery since this signal drops in amplitude with every possible start pause in contrast to the engine released signal.

This may further result in damage to components of the system. If an extension of the data connection line is required, only the serial cable between DPC and notebook/pc may be extended. NOTE Unplug the DPC after configuration to ensure a safe operation! If the DPC remains plugged into the easygen-300 unit, a safe operation of the unit can not be guaranteed. Woodward Page 61/114

62 If you want to edit the configuration file in order to inhibit resetting the counters, you have to proceed as follows: Open the configuration file in a text editor _NEW_EASYG350X_x20002_pDirUS.asm Delete the lines which are used to display the counter entries in the LeoPC1 configuration The lines to be deleted in the *.asm file are: ;!K <b> <color=ee0000> --CONFIG.COUNTERS---</b> %TAB 0,0,0,H'03;!z2550,"> Maintenance hours","0000h",1.0,0,9999 %TAB 0,0,0,H'03;!M2562,"> reset maintenance period h",h'ffff,2,"no","yes" %TAB 0,0,0,H'03;!l2515,"> Counter value preset"," ",1.0 %TAB 0,0,0,H'03;!M2554,"> Set operation hours",h'ffff,2,"no","yes" %TAB 0,0,0,H'03;!z2540,"> Number of starts","00000",1.0,0,65535 Store the modified file Editing the Configuration File In order to edit the configuration file, open the respective *.asm file in the "Tools" subdirectory of your LeoPC1 installation path with a text editor like Microsoft Notepad. An example of a name (depending on unit and software version) for a configuration file is: Store the modified configuration file back to the "Tools" subdirectory of your LeoPC1 installation path under the same file name. If you load the modified file in LeoPC1 now, the deleted lines will not be displayed in the configuration menu anymore. Configuring the Flags The easygen-300 series provides four configurable LED flags in the alphanumerical display to indicate alarms. One or more alarm messages can be assigned to each one of these flags (i.e. the respective flag will be illuminated if the configured alarm state(s) occur(s) in addition to the regular alarm indication). A detailed description of these flags can be found in the chapter Alarm Messages on page 38. The configuration parameter is described in detail under Flags on page 86. The flags may only be configured using LeoPC1. Configurable display flag 4 Configurable display flag 3 Configurable display flag 2 Configurable display flag 1 Figure 9-1: Configurable display flags Page 62/114 Woodward

63 The flag parameters are displayed in LeoPC1 (refer to Configuration Using the PC on page 61 and the LeoPC1 user manual for more information) under System Codes like shown in Figure 9-2 in default state (alarm "Start fail" is assigned to flag 1). The parameter with the name "Flag 1 Start fail" has the value "Yes", i.e. the alarm "Start fail" is assigned to flag 1. Figure 9-2: Flag configuration default You may assign as many alarms as required to one flag using LeoPC1. Just mark the respective entry and press Input to configure the alarm assignment or double-click the entry for configuration. The example in Figure 9-3 shows that the alarms "Unintended stop" and "Start fail" are assigned to flag 1, i.e. the flag is illuminated (flashing) if at least one of these alarms is present.

82 Discrete Inputs The easygen-300 series has 5 discrete inputs (DI1 to DI5). The discrete inputs 1 & 2 are pre-defined as alarm in- puts for oil pressure (DI1) and coolant temperature (DI2). The discrete input 3 is a control input for remote start. The functions of the discrete inputs 4 and 5 are dependent on the parameter Ignore CB reply (see page 66). If this parameter is set to NO, these discrete inputs are configured as reply inputs for MCB (DI4) and GCB (DI5). Any ch anges made to the settings of the discrete inputs DI4 and DI5 have no effect. If this parameter is set to YES, these inputs can be configur ed freely with the following parameters using LeoPC1. DI {x} operation DI {x} Funktiont L DI {x} d elay DI {x} Verzögerungt L N E DI {x} alarm class DI {x} Alarmklasset L Discrete Input DI {x} operation N.O. / N.C. The discrete inp ut can be operated by a Normally Open contact or a Normally Closed contact. The Normally Closed contact input can be use to monitor for a broken wire. A positive or negative voltage potential can be applied. N.O.... The discrete input is analyzed as "present" by energizing a voltage potential (N.O. / operating current). N.C.... The discrete input is analyzed as "present" by de-energizing a voltage potential (N.C. / idle current). Discrete Input DI {x} delay 0.02 to s A delay time in seconds may be assigned to each alarm input. The fault condition must be continuously present for the delay time at the input before tripping oc- curs. Discrete Input DI {x} alarm class see chapter Alarm Classes on page 93. A / B / C / D / E / F / Control An alarm class can be assigned to a discrete input. The alarm class is initiated when the discrete input receives a triggering signal. Only alarm classes B and F are implemented in the easygen. If "control" has been configured as the alarm class, the discrete input can be evaluated by the relay outputs if configured accordingly (see Relay Outputs on page 83 for more information).

88 Chapter 11. Event Logger The event logger is a FIFO (First In/First Out) memory for logging alarm events and operation states of the unit. The capacity of the event logger is 15 entries. Additional event messages overwrite the oldest messages. Since the easygen 300 units do not include a clock module, the operating hours are stored with each event logger entry as the timestamp. The individual alarm messages, which are stored in the event history, are described in detail under Alarm Mesn page 89. sages on page 38. The operation states, which are stored in the event history, are listed in Table 11-1 o NOTE The event logger cannot be read out directly from the front of the unit. It can only be read out using the program GetEventLog, which can either be used as a stand alone or within LeoPC1. GetEvent Log Software Installing GetEventLog GetEventLog can either be used as a stand alone or within LeoPC1. In order t o call it up from LeoPC1, it must be installed into the LeoPC1 installatio n path. To install GetEventLog, start GetEventLog_vxxxxx.exe from the GetEventLog directory on the CD delivered with the unit. If you want to use GetEventLog from inside LeoPC1, it must be installed into the LeoPC1 installation directory. Starting GetEventLog Connect the easygen to a free COM port on your computer using the DPC as described under Configuration Us- After starting GetEventLog for the first time, you must configure the communication settings. To do this, select ing the PC on page 61. Start GetEventLog directly or call it up by selecting GetEventLog from the menu Tools in LeoPC1. the Interface tab, configure the COM port according to the port, to which you have connected the DPC, and enter the other settings as represented in figure Figure 11-1 since these are the default settings of the easygen 300. Figure 11-1: GetEventLog - interface configuration Reading Out GetEventLog On the Eventlog tab of GetEventLog, click the Request Eventlog button to read out the content of the event logger memory. The content of the event logger is displayed as shown in Figure Page 88/114 Woodward

89 Figure 11-2: GetEventLog event logger content The 15 latest events are displayed in chronological order and each entry is composed like this: "sign";"operating hour";"alarm/state" whereas "sign""+" indicates the occurrence and "-" indi cates the disappearance or acknowledgement of the alarm or state "operating hour" serves as a timestamp and indicates the operating hour of the event occurred "alarm/state" indicates the type of alarm or change of state that occurred The alarm codes are the same as displayed on the unit and described under Alarm Messages on page 38. The codes for the operation states are indicated in Table 11-1 below. Example: The entry "+";" h";"00031A" means that alarm 31A unintended stop "00031A" oc- hours are indicated in decimals, i.e. 8.4 hours are curred "+" at operating hour 8.4 " h".
